ADDING FRACTIONS WITH LIKE DENOMINATOR
5/12+3/12
DO YOU KNOW THE ANSWER?

8/12 = 2/3

Step-by-step explanation:

5/12 + 3/12

Since the denominator is the same, we add the numerators

8/12

We can simplify by dividing the top and bottom by 4

2/3

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
